Be it known that I, 'FREDERIK Gr. VliirrA TING'roN, a citizen of the United States, residing in Evanston, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Bumpers, of which the following is a speciication, 'reference being ad to the accompanying drawings, forming a part thereof'.

lo This invention relates to supporting means or automobile bumpers and' its purpose is to provide for readily moving the transverse impact bar out of its normal position when desired, as for example, when the bumper is mounted at the rear of an automobile and would otherwise prevent or embarrass re moval of a spare wheel or tire carried between the body and the impact bar. The-invention consists of certain details of construction and their combination hereinafter described and shown in the drawing, as indicated by the claims.

ln the drawings Figure 1 is a topf plan view of a bumper constructed in accordance with this invention shown in position of use.

` Figure 2 is a side elevation of the parte shown in Figure Figure 3 is a side elevation showing the i 3o bumper swung about its pivotal mounting to avoid obstructing the spare wheel or tire.

As illustrated, the bumper. comprises an impact bar, l, oiiat spring metal with reflexed supporting arms, 2, which are secured vto the impact bar, 1, by means of clamped clips., The arms, 2, are themselves carried by dat supporting arms, 4, attached to the rear end portions of the vehicle side 'frame members 5, by any! convenient means 4o such as hook bolts, 6. The supporting arms, 2,.are pivotally connected to the arms, Li, by lined in the said supporting arma-@but pivotal action about the bolts, 7 is normally prevented by the presence of locking bolts, 8, fixed the arms, 2, an engaging open ended slots, 9, in the respective arms,/I Forrthe pivots, 7, the inner 'ends' of. the arms, 2, are slotted at 10, so that upon loosening'the'nutsof the bolts, 7 and 5o.4 8, the arms, 2, maybefslidupon the arms, et. to tbeextent of theslots, 10, so as to free' theloclzing. bolts,`8=,"irom the open ended -blots, 9, andipermit the arms, 2, and the impact bar, l, to be swung down about the pivots, 7, as shown in Figure 3.-"1Thus'ii` a or EvANs'roN,

spare wheel or tire is supportedat the' rear of the vehicle in the position indicated at A, so that it must be withdrawn transversely of the normal bar, l, this pivotal movement of the bar will carry it clear of the path of such withdrawal of the wheel or tire; and the bumper may bev quickly ive-adjusted byl 'merely swinging it back, sliding the bolts, 8, into the slots, 9, and again tightening the nuts on bolts, 7 and S.

I claimizfl. In combination with a vehicle frame, a bumper comprising an impact bar and a pair of two-part supporting arms', one part 'of each arm 'being rigidly attached to the frame and the other being fixed to the impact bar, the two parts being lapped upon each other with a pivot and a bolt connectind them, said pivot andbolt each engaging a ongitudinal slot in one part and one of said Aslots being formed as a notch at the endwise thereof to bolt from the slot by siidin one part upon the other. 2. 1n te combination defined in claim l, the other slot being formed in the'other part and closed at both ends to prevent complete detachment of the parts when the bolt is disengaged i'rom the notch'.

3. In the combination deiined in claim 1, said pivot being also a bolt for clamping the end of the part opening A parts firmly together.

4. In the combination defined in claimv 1, said two parts oi each supporting arm being formed of fiat stock set vertically on edge and lapped face to face in substantial alignment when the bolt engages the notch.

5. In combination with a vehicle frame,^a

bumper comprising an impact bar and a pair` of two-part supporting arms,

one part of each arm being rigidly attached to the frame and the other being pact bar, the two parts being lapped upon each other with a pivot and a bolt connecting them, said pivot and bolt each engaging' a longitudinal slot in one part and one of said slots being formed as a notch opening through the edge of the part topermit disengaging the bolt from said notch and `swinging-the part about the pivot.A

6. ln combination with a vehicle frame, a bumper comprising an impact bar and a pair of two-part supporting arms, one part of each arm being rigidly attached to the position of the impact iixed to the imicsl 1.0 pivot frame and the other being ixed to the impact bar,v the two parts being eipped upon each other with a pair of "fasteners connecting` them, Said. fuseners euch engaging zr ongitudnai' Slot in one part und one of the slotsbeing formed :is zi notch' opening through the end of the part to permit iisengaging the fastener therefrom :md swinging the Part about the other fastener :1S a
